JDeveloper 3.1 and JDK1.2.2: are they REALLY compliant?

Hi,
I've already been developing in JDev 3.0 using Java 1.1.8 for a few months and have a number of EJB's deployed in an Oracle8i 8.1.5 database. These are accessed by a servlet which is called from a C++ application in order to populate the db tables. I'm using Java Webserver 2.0 and everything works fine.
I've been upgrading to Java 2 with JDev 3.1, Oracle 8i R2, and JDK1.2.2. Everything again works fine when I am testing and debugging in the JDev 3.1 IDE but when I deploy to the Web server, my context lookup for the EJB published name freezes, returns an error status to the C++ app but does not display any error/exception msgs in the server console/log files.
On investigating I found that the java.exe bundled with JDev 3.1 as the JDK1.2.2 version is actually NOT the java.exe that has been dispatched with the release version of JDK1.2.2! There are however two files in the bin directory of the JDK1.2.2 called oldjava.exe and oldjavaw.exe which correspond to the ones bundled with JDev 3.1?
Could someone please explain what is going on? As it stands at the moment the version of java.exe with JDK1.2.2 does not work for my EJB's but if I replace it with the oldjava.exe, it works fine. Does this mean that JDev 3.1 is NOT actually JDK1.2.2 compliant or have I done something wrong?
This is potentially a major problem for our projects so if anyone at Oracle has any info it would be greatly appreciated.
Cheers
Dave

David,

Which means that there is a difference relative to the VM version.
All the names are correct on 8i deployment. And all necessary files are on classpath, (including the EJB source and generated jars, that are also in the /lib on the context dochome).
Any thoughts?

Log4j and log4cxx together

Hi,
I'm using RollingFileAppender to append log4j and log4cxx logs in a common log file. This works only for the first log file. But, the subsequent log files which got created when the size exceeds the specified range, does not getting appended the log4cxx logs.
I have referred http://www.dreamcubes.com/blog/?itemid=59#nucleus_cf
Here is my config settings
log4j:

Logger experts,
First of all, trying to point a common logging file from two different log configuration file is possible?
If this is not at all possible, Keeping the two different log file would work, but it is cumbersome on debugging..
Thanks and Regards,
Ramesh

Log4j and WAS logging

Hello all,
Is there anyway to redirect log4j logging to WAS loggers.
For example, axis needs log4j and may need to log to some appenders.
Can we safely use SAP logging and how?
Is there an example somewhere?
Antoine

There's an article "Integrating 3rd party logging Frameworks into SAP NetWeaver" (https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/36085e78-0801-0010-678d-8b4e89ddff3c)
It mentions sample code and a tutorial for a "Log4j bridge", but I couldn't locate that. I have posted a separate question for that.
Hope this helps,
Michael

Log4j and Jboss are acting weird

This question is reagards to Log4j and JBoss and I thought this is the best place to ask this question.
I am using Jboss 3.2.3. My purpose was to log messages in a seperate file "developer.log" using Log4j. These messages has to be logged in this file only. So in my WAR's folder under WEB-INF/classes I created a file log4j.properties:
log4j.logger.standard=DEBUG, devlog
log4j.appender.devlog=org.apache.log4j.RollingFileAppender
log4j.appender.devlog.File=C:/logs/developer.log
log4j.appender.devlog.layout=org.apache.log4j.PatternLayout
log4j.appender.devlog.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%nNow my code :
import org.apache.log4j.Logger;
private static Logger log = Logger.getLogger("standard");
log.debug("a debug message");
log.info("a info message");
log.warn("a war message");I test run this code without Jboss and it works perfect. It created a file "developer.log" in the desired location and logs messages in it.
Now i run with JBoss. JBoss does not create "developer.log" file at all. Instead it logs all the messages in server.log
2005-09-30 23:07:35,459 DEBUG [standard] a debug message
Jboss is recognizing that it is standard but after that it is not gving me the desired results. Any input on how to fix this problem?
TIA

You can tell it you don't want to inherit, by adding
this to your "standard" category tag:
<category name="standard" additivity="false">
thanks. it works perfect.
ok i got it working kind of. Jboss already comeswith
a log4j.xml so i put my log4j stuff in this file :You should be able to deploy your own log4j.xml with
your app's resource files and make it use yours when
it is running your app.Ok I took out my stuff from Jboss log4j.xml, create a new xml progtest.log4j.xml like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="false">
<appender name="DEVLOG" class="org.apache.log4j.RollingFileAppender">
    <param name="File" value="${jboss.server.home.dir}/log/developer.log" />
    <param name="Append" value="true" />
    <layout class="org.apache.log4j.PatternLayout">
      <param name="ConversionPattern" value="%d{ABSOLUTE} %5p %c{1}:%L - %m%n" />
    </layout>
</appender>
<category name="standard" additivity="false">
    <priority value="INFO"/>
    <appender-ref ref="DEVLOG" />
</category>
</log4j:configuration>My web application is in a ProgTest.WAR folder. I put the above file "progtest.log4j.xml" under WEB-INF/classes in ProgTest.WAR folder. When i run the app the very first problem again arises that no developer.log file was created; instead the concerned messages were put into server.log and console.
All my classes are in one jar file. I include progtest.log4j.xml in that jar file, redeploy it and test it but still the same problem.
What i am doing wrong here?
Thanks

Weblogic NT Service 4.5.1 and Jdk1.2.2

I am trying to set up the Weblogic NT Service with 4.5.1 SP9 and
jdk1.2.2.
When I use t3config to set up my JAVA_HOME with e:\jdk1.2.2 instead of
using the -jre 1.2 I get an error saying that javai.dll can't be found.
The problem is javai.dll is a jdk1.1.7B module. Has anyone else had
this problem.
Thanks,

It doesn't even get that far, java.exe can't start because it is looking for
a jdk1.1.7b dll

I think you had jdk1.1.7B installed before, right?.

Log4J and LogConfigurationException...

I get an error when I try to deploy an old application to the newly updated Oracle Application Server 10.1.3. It has something to do with Log4J, and I've tried a lot of different things, but nothing seems to help.

Difference between jdk1.3 and jdk1.4 and jdk1.5

Hi All
1: I wud like to know the difference between jdk1.3 and jdk1.4 and jdk1.5. I could not recoginze the correct answer for this.. mostly i need the added advantages for version of JDK..
2: I wud also like to know difference in J2SE and J2EE.
Thanks in advance

while I can't tell you exclusively the differences, other than more methods have been added and some have been deprecated, from version to version, that is at least one difference.
I know several like me are reluctant at the moment to jump on up to 1.5, for fear of (and reasonably so) making their current apps go haywire!
Mine did just the other day when I tried to upgrade the JDK from 1.4.0 to 1.4.2.12!! It hosed everything.
J2SE is the Standard Environment, and J2EE is the Enterprise environment, which at the very least allows for things like the java Mail interface, using servlets and classes with the HTTP environment!
I'm sure many other posters could more accurately and specifically give you some other criterion of differences and advantages.

JDev 10.1.3 and JDK1.2.2 use javac problem

I have an old application that I need to compile in 1.2.2, and have tried the "use javac" checkbox on the project properties compile page. The compiler seems to run, but there is an intential error in the code. I put it there, because the class file didn't seem to get generated. I tried this on command line, and apparently '-source' is an invalid option in 1.2.2.
E:\jdk1.2.2\bin\javac.exe -J-mx512m -verbose -source 1.2 -target 1.2 -encoding Cp1252 -g -classpath E:\jdk1.2.2\jre\lib\rt.jar;E:\jdk1.2.2\jre\lib\i18n.jar;E:\jdk1.2.2\jre\classes;E:\app\codebase;E:\oracle\jdev1013\j2ee\home\lib\ojsp.jar;E:\oracle\jdev1013\j2ee\home\jsp\lib\taglib\ojsputil.jar;E:\oracle\jdev1013\j2ee\home\oc4j.jar;E:\oracle\jdev1013\j2ee\home\lib\oc4j-internal.jar;E:\oracle\jdev1013\j2ee\home\lib\servlet.jar;E:\oracle\jdev1013\jdev\lib\ojc.jar -sourcepath E:\app\src -d E:\PTC\Windchill\codebase @C:\DOCUME~1\gteft\LOCALS~1\Temp\javac30279.tmp
[1:53:55 PM] Successful compilation: 0 errors, 0 warnings.
Has anyone else run into this?
Any help or thoughts on how to adjust this behavior for 1.2.2's javac would be appreciated.

Thank you for responding. I am aware of (and frustrated by) issues and limitations due to this application's dependancies on an aging platform, and would upgrade if it were my choice. The dependancy is in the vendor's API, and not in code that I can change.
As the invalid option was not captured as a message or counted as an error, I thought that perhaps this could be a potential issue for using javac with any version.
I was hoping to see if there were additional settings controlling the command line options that I couldn't find.
Thanks,
Greg

Installation failed with Windows Vista and JDK1.602

Hi All,
Appreciate any help to resolve the following installation error on my Windows Vista system with JDK1.602
Pop-up Error Message:
The installer is unable to run graphical mode. Please check the value of the DISPLAY environment varibale.
Thanks,
CP

JSE8.1 (based on NetBeans 5.0) is not supported on Vista. You may want to consider using the latest NetBeans 5.5.1. (NetBeans is where all future development is planned for).
http://forum.java.sun.com/thread.jspa?threadID=5192837
From the release notes of NB551:
# Issue #85361: NetBeans 5.5 installer does not start on Windows Vista.
    Description: On systems running Windows Vista, the NetBeans 5.5 installer fails to start
and a message suggesting running with the "silent" or "console" flag appears.
    Workaround: To correct this, run the installer on JDK 6.0 build 96 or newer.
    If you encounter further difficulties, disable Compatibility Mode manually. You can do
this by right-clicking the .exe installer file and choosing Properties from the pop-up menu,
then deselecting Compatibility Mode in the Compatibility tab of the File Properties dialog.
Note that if Compatibility Mode was turned on automatically, it is necessary to disable it
for both the current user AND all users. To do so, click the "Show Settings for All Users"
button, then deselect the Compatibility Mode checkbox in the "Compatibility for All Users"
dialog.You can try the same workaround for installing jse8.1, to see if that works. But, it is an older version that is not supported on vista and hence my suggestion to consider a later version of NB.

Much appreciated your reply, I used both Windows and Unix system and Ant to build EJB, both CLASSPATH and PATH are configured to Jdk 1.5 version.
CLASSPATH=C:\bea\jdk150_06\lib and PATH=C:\bea\jdk150_06\bin, and verify that it is 1.5 not 1.4 version.

I'm trying to use JDeveloper 10.1.3.5.0 with jdk1.7.0_06 and i'm getting the error "Unable to launch the Java Virtual Machine" at path... when trying to launch JDeveloper.
I checked the path and jvm.dll is on the right path : path\jdk1.7.0_06\jre\bin\client\jvm.dll.
I changed the jdev.conf with SetJavaHome set to path\jdk1.7.0_06.
What other configuration should I make ?
How do I know which Java version is supported by this version of JDeveloper ?
Thank you for your help...
Cheuyi

Read the install guide for your version and you'll see that 10.1.3 is not certified with JDK 1.7
Try using JDeveloper 11.1.1.6 instead.

Log4j and Tomcat-problem

Hi all,
First I tried to add some logging to my simple Java code with a xml configuration file and it worked fine.
Now I am trying to add logging to the whole java application in the same way which runs in tomcat and face with the foll problem.Tomcat is not able to find the configuration file.I tried to place the xml file in all feasible locations in tomcat and also tried to add in classpath but in vain.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~`
Java Code(Which gets called in startup by another code)
Java Code
public class PublisherPoll implements Runnable {
public static Logger logger = Logger.getLoggerPublisherPoll.class);//***********log4j
public static Logger getLoggerInstance(){ //***********log4j
return logger;
static{
DOMConfigurator.configure("sudarson.xml");//**********its telling it cant find/open this xml file
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Error(during starting tomcat)
log4j:ERROR Could not open [sudarson.xml].

DOMConfigurator.configure("sudarson.xml");//**********its telling it cant find/open this xml fileWhat does "sudarson.xml" mean to you? To me, it means a file name relative to the current directory. What do you think the current directory is when you're running this in Tomcat?
You need to research the APIs more fully, to figure out how to give it a resource name relative to the application's classpath, and put that file in said classpath.
If I were you, I would try to avoid explicitly calling DOMConfigurator.configure altogether, and just pass the appropriate Log4J system property to the commandline that starts up Tomcat. Let Log4J worry about loading the file, given the property. If I recall correctly, the system property name is "log4j.configuration", which defaults to "log4j.properties" if unspecified. Also, rather than have each application running in Tomcat have their own log4j configuration file name, I'd name them something more universal, like "log4j.xml" - then if you deploy multiple apps in Tomcat, they can all load their own log4j.xml file, as long as (again) you corrected the "log4j.configuration" system property.

JTable 's tableChanged() works differently in jdk1.2.2 and jdk1.3

While updating the contents of the jtable I am using the following
table.tableChanged(new TableModelEvent(model));
table.repaint();
In jdk1.2.2, this updates the contents and repaints the table without clearing the row selection
But the same in jdk1.3 updates and repaints the table but clears the row selection.
How can I overcome with problem.
I also tried model.fireTableStructurChanged();
along with this but it works in jdk1.2.2 and not in jdk1.3.
Any suggestion is greatly appreciated.
Thanks

They have fixed a bug. If you are replacing the whole table, then the row selection for the old table doesn't mean anything for the new table. In fact, that row might not even exist any more.
